<h2>Import L2 Data Product</h2>

<h3>Ocean Level-2 Data Products</h3>
<p>The L2 data product reader supports data from a number of missions, processed via the NASA l2gen processing code.</p>
<ul>
    <li>SeaWiFS</li>
    <li>CZCS</li>
    <li>OCTS</li>
    <li>MOS</li>
    <li>OSMI</li>

    <li>MODIS</li>
    <li>MERIS</li>
    <li>VIIRS</li>
</ul>


<p>
    Each Level-2 product is generated from a corresponding Level-1A product.The main data contents of the product are
    the geophysical values for each pixel,derived from the Level-1A raw radiance counts by applying the sensor
    calibration, atmospheric corrections, and bio-optical algorithms. Each Level-2 product corresponds exactly in
    geographical coverage (scan-line and pixel extent) to that of its parent Level-1A product and is stored in one
    physical HDFfile.

    The standard Ocean Color product contains 12 geophysical values derived for each pixel: six water-leaving radiances
    for bands 1 to 6, the chlorophyll a concentration, the diffuse attenuation coefficient at band 3, the epsilon value
    for the aerosol correction of bands 7 and 8, the angstrom coefficient for bands 4 and 8, and the aerosol optical
    thickness at band 8. The standard SST product contains 11-micron and 4-micron (nighttime only) SST for each pixel.
    In addition, 32 flags are associated with each pixel indicating if any algorithm failures or warning conditions
    occurred for that pixel.
